SPECIFICATION forming part of Letters PatentNo. 283,695, dated August21, 1883.

Application anarch 11,1883. (N0 model.)

To all whom it may concern.-

Be it known that I, CONSTANT W. BOOTH, a citizen of the UnitedStates,,residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improve. ments in Lubricators, ofwhich the following is a specification.

This invention relates to that class of lubricators in which steam isadmitted to the upper portion of the oil-chamber through a verticalpassage for discharging the oil at the bottom of the chamber through asecond vertical pas sage, the'flow of the steam and oil being regulatedby a cock which is common to both passages.

The novel feature of my lubricator is the construction and arrangementof the cock, as hereinafter describcd,and as-illustratcd in theaccompanying drawings, in which- Figure 1 represents a sectional sideelevation, and Fig. 2 a cross-section.

Similar letters indicate corresponding parts.

The letter A designates the shell of alubricator,comprising theoil-chamber B and two vertical passages, G D, one serving to admit Isteam to the upper part of the chamber and the other to discharge theoil at the bottom. Said passages G D extend of the chamber. v th rough acentral stem, E, formed on' the lower 'part of the shell A to supportthe lubricator,

and also extend through the bottom of the oilchainber, while theoilpassagc O is properly elongated by a tube rising to a point near thetop of the chamber; In that portion of the shell A constituting thebottom of the oilchamber is a socket, F, which opens in a lateraldirection and intersects the vertical passages O D, and into which isfitted a cock, G, having two ways, C D, adapted to register with saidpassages. The socket F isenla-rged at the outer 'or open end to form ashoulder, 0, near such end, and is provided with a screwthread in itsenlarged part to receive a screwring, I, whichvis fitted snugly to thestem G of the cock. At the junction of the stem G with the cock isjform'ed a shoulder, s, which is substantially flush with the shoulder oof the socket, and forms,together' with said shoulder o,a seat forapacking, J,which is clamped in position by the screw-ring I, thusforming a tight joint betweenthe cock and socket.

, The cock Ghas heretofore been fitted in a 1 socket formed in the stemE of the shell; but this arrangement thereof renders it necessary toprovide the stem with a laterally-proj ecting neck, which, if made inone piece with the shell, prevents its being turned in alathe, which isnecessary to the economical manufacture of the lubricator, and if madeseparate from the, shell is extremely weak and liable to twist or break.A cock has also heretofore been arranged at a point intermediate of thetop and bottom of the oil-chamber; but in this position thereofconsiderable difficulty is had in casting the shell with a socket toreceive the cock, and hence the apparatus is expensive to manufacture,while such cock, moreover, interferes with the free flow or circulationof the oil, and materially decreases the area of the chamber. the cock Gin the bottom of the oilchamber, and entirely above the stem E and belowthe body of the chamber, I am enabled to turn as well as to cast theshell without difficulty,

and at the same time render the cock very effective in operation.

What I claim, and desire to secure by Letters Patent, is-

The combination, substantially as v hereinbcfore set forth, of the shellforming the oil- 8 chambcr,provided with. vertical passagescommunicating with the oil-chamber and with a lateral socket in thebottom of the oilchamber, such socket intersecting the vertical passagesand having its outer end enlarged in di- 8 ameter to form the shouldero, the two-way cock fitted into the socket and provided with twoparallel ways, also with the shoulder s flush with the shoulder of thesocket, the packing, and the screw-ring arranged in the en- 9 CONSTANTW.
